The chart generated every user's password at render time into <release>-credentials, which tenants could read again at any time and which Helm history kept for MaxHistory revisions, so a deployment whose policy requires a credential shown once could not run PostgreSQL here. The accounts move under CloudNativePG's managed roles, each pointing at the account Secret the Cozystack API seeds, so the operator creates the role with the SCRAM verifier the Secret holds and applies a changed Secret live, and a password set inside PostgreSQL is reverted. Every role is rendered as the init-script created it, because the operator reverts an attribute that differs, revokes a parent role missing from inRoles and clears a comment the spec leaves unset, while the init-script still finds the roles to drop by that comment and by membership in the marker. The init-script stops creating, passwording and altering accounts, where it would be a second writer, and keeps the two things the operator has no field for: the marker membership narrowed to a record, and createrole_self_grant. The refusal to adopt a role the chart did not mark moves into a pre-upgrade hook, because the operator adopts a managed role within seconds of the spec reaching it and the post-upgrade init-job would find it adopted already. The definition declares the credentials block, so the API seeds, serves and mints for the kind, and no longer selects the credentials Secret, which the chart no longer renders or grants. BREAKING CHANGE: PostgreSQL passwords are no longer readable from <release>-credentials. A password is issued once, by a mint on the account's Credential in core.cozystack.io, and replaced by the next mint; deleting a Postgres application whose release is suspended is refused. The conversion needs a platform variant with migrations enabled. Assisted-by: LLM Signed-off-by: Timofei Larkin <lllamnyp@gmail.com>
Chainsaw E2E tests
The Cozystack E2E app suite, written for Kyverno Chainsaw — a declarative, Kubernetes-native E2E test framework (CNCF, part of the Kyverno project; successor to KUTTL).
This directory replaces the per-app BATS suite that used to live in hack/e2e-apps/*.bats. The CI e2e job runs every suite under hack/e2e-chainsaw/ through hack/e2e-chainsaw-run.sh after make install-cozystack; cluster bootstrap (hack/e2e-prepare-cluster-container.bats, hack/e2e-install-cozystack.bats) and the OpenAPI checks (hack/e2e-test-openapi.bats) remain BATS.

What Chainsaw buys over the BATS suite
- Readable tests — a list of resources and expected states, not shell control flow. The
timeout N sh -ec "until kubectl get ..."+kubectl waitpair that appeared ~100 times collapses into a singleassertthat polls existence and state together. - Distinguishable failure modes — "object never created", "created but never ready", and "wrong status" all surface as a structured diff instead of an opaque shell timeout.
- Automatic diagnostics —
catchblocks dump events,describe, and pod logs on any failure (the BATS suite only did this inharbor.bats, by hand). - Automatic cleanup — resources Chainsaw applied are deleted (and waited on) in reverse order;
finallycovers operator-created leftovers. - CI-ready output — a JUnit
chainsaw-report.xmlis emitted for the test summary.
Test anatomy
Each suite is a directory with a chainsaw-test.yaml (one or more Test docs) plus the manifests it applies. A step has try (operations: apply, assert, error, script, delete, …), optional catch (diagnostics on failure), and optional finally (teardown regardless of outcome).
Declarative suites assert on status.conditions and concrete fields. Inherently imperative suites keep their logic in script steps:
- openbao —
bao operator init/unsealviakubectl exec. - kuberture —
jqon Service annotations + external-dns split-horizon log assertions. - vminstance — a server-side dry-run eviction of the VM's launcher pod, checked against the VMI's
LiveMigratablecondition. - gateway — admission-rejection cases that need
kubectl --asimpersonation or error-message greps; the tenant apex is read from the namespacenamespace.cozystack.io/hostlabel at runtime so they pass on any host. - kubernetes-latest/previous — wrap
_lib/run-kubernetes.sh(Kamaji bringup, port-forward, LB/NFS/ouroboros). The scriptcds to the repo root (the test dir ishack/e2e-chainsaw/<suite>, so repo root is../../..).
Conventions / gotchas (Chainsaw v0.2.15)
- Condition asserts use the filter-as-list form, not the documented
[0]index:Thestatus: (conditions[?type == 'Ready']): - status: "True"(conditions[?type == 'Ready'])[0]: {status: "True"}idiom fails with "field not found in the input object". - A reading of a failure diff: the "actual" side is a projection onto the expected fields —
status: {}means the JMESPath expression failed, not that status is empty. Read the error line above the diff first. errorwith a bare resource ref (name only) asserts the resource does not exist (used for "PVC reclaimed", "no backup schedule", "child has no Gateway HR").scriptruns in the test directory with$NAMESPACEset to the config namespace (tenant-test).
Running locally
Requires a cluster with Cozystack installed and a tenant-test namespace (the environment hack/e2e-install-cozystack.bats produces). bucket and seaweedfs additionally need mc, nc, and jq on the host; kuberture/openbao/foundationdb/securitygroup/computeplane/kubernetes-latest/kubernetes-previous/vminstance need jq.
# install chainsaw
go install github.com/kyverno/chainsaw@latest # or: brew install kyverno/chainsaw/chainsaw
# run all suites (config picked up from .chainsaw.yaml)
cd hack/e2e-chainsaw
chainsaw test
# run a single suite
chainsaw test postgres/
kubernetes-latest/kubernetes-previous each bring up a full tenant Kubernetes cluster (~25 min, real worker nodes) and vminstance boots a nested VM — expect a long run for the full set.
CI integration
The e2e job in .github/workflows/pull-requests.yaml runs make -C packages/core/testing test-chainsaw (which execs hack/e2e-chainsaw-run.sh inside the e2e sandbox) and uploads chainsaw-report.xml. The runner calls chainsaw test once per suite directory, fails a suite whose pods outlive its cleanup by more than the default timeouts.cleanup (LEAKED-PODS suite=<dir> in the log; see docs/agents/e2e-testing.md §8 and _lib/leak-allowlist.txt for known, filed leaks), and merges the per-suite reports into that one file. A local chainsaw test as shown above runs the same tests without the leak check. The sandbox image (packages/core/testing/images/e2e-sandbox/Dockerfile) ships the chainsaw binary alongside kubectl/helm/mc/jq/nc, built from source with a patch that keeps an assert polling through transient API errors such as an etcd leader change; a released chainsaw run locally fails the assert on the first such error instead.
